Cohen says he'd like to know if tax prep problems are widespread, "The main thing we look for in the hearing is to see how prevalent the circumstances with tax frauds, and or people taking other identities to get their checks."

Cohen says ultimately what he hopes comes from the hearing is one of three things.

Stronger criminal laws, more funding to promote free, IRS tax preparation, or "Maybe more funding into IRS agents to police this thing, this type of industry."
